Zürich's Ephrem Lüchinger (keys) and Manuel Rindlisbacher (bass) are Ephma, and this is their first release. A Walking Letter can sound industrial, have a touch of jazz, be celestial or totally electro, and, at times, groovy enough to dance to. Ethnic instruments are peppered with voices and rhythmic samples of everyday noises. You certainly won't fall asleep on your sofa, on the contrary, some of you clubbers, who think you have heard it all, might even prick up your ears.
